Christchurch, New Zealand, suffered another Earthquake today, less powerful than the last, but much closer to the surface, causing much more damage and many casualties. Our thoughts go out to everyone in Christchurch, their friends and families.

All the best for those in that beautiful city. Shallow quakes are no fun at all - having lost my home to one years ago. Hopefully all our NZers can chime in when they've got the chance and confirm they're OK...especially anyone from the Christchurch area.
